JOSEPH A. DANSEREAU, OF WOOfiSOOKET, RHODE ISLAND.

PLATE-LIFTER.

SPECIFICATION forming part of Letters Patent No. 7 21,865, dated March 3, 1903.

Application filed August 15, 1902.

To all whom it may concern.-

Be it known that I, JOSEPH A. DANSEREAU, a citizen of the United States, residing at Woonsocket, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Plate -Lifters, of which the following is a specification.

My invention relates to improvements in plate-lifters; and it consists in the peculiar and advantageous construction hereinafter described, and particularly pointed out in the claim appended.

In the accompanying drawings, Figure 1 is a perspective View illustrating the manner in which my improved lifter engages a plate, the plate being shown by broken lines. Fig. 2 is an enlarged detail perspective view illustrating the manner in which the shanks of the jaws of the device are pivotally connected and the application of the spring for moving the jaws apart and normally holding them apart.

Similar letters of reference designate corresponding parts in both views of the drawings, referring to which- A B are the jaws of my improved plate lifter, each of which is preferably made of a single piece of wire, as shown, and comprises upper and lower longitudinal portions a b, curved to conform to the edge of a plate, and outwardly-extending end loops 0, designed to receive the edge of the plate. I The end of the portion of wire forming the inner loop 0 of the jaw A is bent around the portion a, of said jaw and carried rearwardly to form the shank A thereof. This shank A comprises a straight portion d, immediately in rear of the jaw A, a portion 6, which extends upwardly at right angles to the portion (1 and is bent to form a lateral loop f, a straight portion g, which extends rearwardly from the upper end of the portion 6, and a portion h, which depends from the rear end of the portion g and terminates, by preference, in a combined hanger-up and stove-lid lifter 't'. Said hanger-up and'lid-lifter is formed by bending the piece of wire into a loop, with a shoulder at the rear thereof, and twisting the end of the piece of wire around the portion h, as indicated by 9.

The end of the portion of wire forming the inner loop a of the jaw B is bentaround the Serial No. 119,734. (No model.)

-portion a thereof and carried rearwardly toform the shank B of the jaw. This shank B is made up of a straight portion k, immediately in rear of the jaw B, a portion Z, which extends upwardly at right angles to the portion It and is bent to form a lateral loop m, a straight portion n, which extends rearwardly from the upper end of the portion Z, a portion 1), which depends from the rear end of the portion n and is bent around the portion h of the shank A, as indicated by q and r, to form bearings for said portion h and pivotally connect the shanks B A together, a straight portion 3, which extends forwardly from the loop or eye 1 and is lapped with the straight portion 7a and bent at taround the same, and a loop u, in which the bent portion 15 terminates, said loop being disposed at right angles to the portions its and having for its purpose to receive and guide the portion dof the shank A so as to retain the jaw A in the same horizontal plane as the jaw B and render the lifter rigid and strong.

The shanks A B form the handle of my improved plate-lifter, and it will be readily observed that when a person grasps said handle and places the thumb in the loop or eye f and the index-finger in the loop or eye m he or she is enabled with the one hand to open the lifter and then press and hold the jaws thereof in engagement with the edge of a plate after the manner shown in Fig. 1, also that the person is enabled with the one hand to conveniently lift and carry the plate. To disengage the lifter from the plate, the user has but to press the shanks outwardly or away from each other. It will further be observed that in virtue of the shank B having the vertical portions Z and p and the upper and lower horizontal portions 'n and s a handle is formed which is adapted to be conveniently grasped by the full hand and is stiff and strong.

I prefer in practice to employ a spring C for moving the jaws A B apart when pressure is removed from the shanks A Baud normally holding said jaws apart. The spring 0 is coiled about the portion h of the shank A and connected at one end thereto, as indicated by 1;, while the arm m at its other end is coiled about or otherwise connected to the portions of the shank B.

WhileI prefer, as stated, to use the spring C, I desire it to be distinctly understood that I do not confine myself to the use of the spring, as the lifter is complete and advantageous Without the same. I

Vhen the spring C is employed, it is simply necessary for the user of the lifter to release the shanks A B in order to etfect the disengagement of the jaws A B from a plate, while to engage a plate the shanks A B must be pressed inwardly against the action of the spring.

I have entered into a detailed description of the construction and relative arrangement of parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear, and exact understanding of the same. I do not desire, however, to be understood as confining myself to such specific construction and relative arrangement of parts,as such changes or modifications may be made in practice as fairly fall within the scope of my invention as claimed.

Having described my invention, what I claim, and desire to secure by Letters Patent, is-

A plate-lifter comprising a jaw formed of wire, and having an integral shank made up of a straight horizontal portion cl immediately in rear of the jaw, a vertical portion e extending upwardly from the rear end of the portion d, and provided with a lateral, vertical loopf, a straight, horizontal portion g extending rearwardly from the upper end of the portion 6, and a vertical portion h depending from the rear end of the portion g, and another jaw formed of wire, and having an integral shank made up ofa straight, horizontal portion 70 immediately in rear of the jaw, a vertical portionl extending upwardly from the rear end of the portion 7a, and provided with a lateral,vertical loop m, a straight, horizontal portion n extending rearwardly from the upper end of portion 1, a vertical portion 1) depending from the rear end of the portion 12, and pivotally connected with the portion 7t of the first-mentioned shank, a straight horizontal portion 3 extending forwardly from the lower end of the portion 19, and wrapped around the portion is, and terminating in a loop u, disposed at right angles to the portion 70, and loosely receiving the portion cl of the first-mentioned shank.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JOSEPH A. DANSEREAU.
